Forum Title: Water pressure spikes
I'm trying to figure out what is causing spikes in my water pressure in my home. i have my PRV set to 45 psi, no expansion tank, no back flow preventer or check valve. Street pressure according to water company is around 90 psi. I've installed a pressure gauge with the red pointer on an outside faucet that shows pressure max and have seen it as high as 90 psi. Just cracking a faucet sends it back to 45 psi. Could my water heater still be the problem? Could my three year old PRV intermittently be leaking by? Should I even worry about this? Thanks, Curtis
